    Abstract: An unmanned aerial vehicle with deployable components (UAVDC) is disclosed. The UAVDC may comprise a fuselage, at least one wing, and at least one control surface. In some embodiments, the UAVDC may further comprise a propulsion means and/or a modular payload. The UAVDC may be configured in a plurality of arrangements. For example, in a compact arrangement, the UAVDC may comprise the at least one wing stowed against the fuselage and the at least one control surface stowed against the fuselage. In a deployed arrangement, the UAVDC may comprise the at least one wing deployed from the fuselage and the least one control surface deployed from the fuselage. In an expanded arrangement, the UAVDC may comprise the at least one wing telescoped to increase a wingspan of the deployed arrangement. The UAVDC may also comprise a foldable propeller blade with a locking mechanism. Foldable propeller blades may have a stowed configuration and a deployed configuration, and the foldable propeller blades may pivot about a hinge to move between configurations. A foldable propeller blade in a deployed configuration may experience forward folding motion due to forces acting upon it. A locking mechanism—for example, a ratchet and pawl—may lock a foldable propeller blade into a configuration. In a locked arrangement, a UAVDC may comprise at least one foldable propeller that locks into place to prevent forward folding tendency.

    Abstract: A tilt wing aircraft has a spaced plurality of wings mounted on a fuselage to pivot in unison about corresponding ones of a parallel plurality of tilt axes, between an upright position and a cruise position. In the cruise position the wings are disposed edge to edge with a gap less than the width of any of the plurality of wings, as measured at the fuselage. A plurality of power units are mounted on one or more of the wings to rotate in unison with them between a vertical propulsion position and a forward propulsion position. Said plurality of power units can rotate into the vertical propulsion position as the wings rotate into the upright position. The wings are placed in an upright position with the power units positioned to provide vertical propulsion. When powered, the power units can create a downdraft between the wings in order to lift the fuselage. The wings and the power units are rotated to reduce their angles of attack and facilitate forward motion of the fuselage.
